Group (Periodic Table) Definition
Group, also known as a family, is a vertical column in the Periodic Table that contains elements with similar properties and trends. There are 18 groups in the modern periodic table, each designated by a number and a unique name.
Noble Gases Belong to Group 18
The elements in Group 18, also known as the noble gases, are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are characterized by their low reactivity and full outer electron shells, making them stable and nonreactive.
Alkali Metals Occupying Group 1
Group 1 is occupied by the alkali metals, including lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are highly reactive and can easily lose their outermost electron to form positive ions.
Group 17 Elements Are Halogens
The elements in Group 17 are known as halogens, which include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are highly reactive nonmetals and readily form compounds with various elements, especially alkali metals.
Transition Metals Occupy Multiple Groups
The transition metals constitute a large portion of the periodic table and occupy multiple groups. They include elements such as iron (Fe), copper (Cu), zinc (Zn), silver (Ag), and gold (Au). Transition metals are known for their variable oxidation states and colorful compounds.
Group 16 Elements Are Known as Chalcogens
The elements in Group 16 are referred to as chalcogens, which include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). Chalcogens have diverse properties and are essential components of many compounds.
Group 2 Elements – Alkaline Earth Metals
Group 2 consists of the alkaline earth metals, such as beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). These metals are less reactive than the alkali metals but still have the tendency to form positive ions.
Lanthanides and Actinides – Separate Sections
The lanthanides and actinides are placed separately at the bottom of the Periodic Table. These elements have unique properties and are commonly referred to as the “rare earth” elements. They often share similar chemical properties within their respective series.
Group 13 Elements Are Called Boron Group
Group 13, also known as the boron group, includes elements such as boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). These elements exhibit a wide range of properties and are used in various applications, from semiconductors to medicine.
The Group Number Indicates the Number of Valence Electrons
The group number in the Periodic Table corresponds to the number of valence electrons an element possesses. Valence electrons are involved in chemical bonding and determine an element’s reactivity and ability to form compounds.
Group 12 Elements – Zinc Group
Group 12 consists of elements known as the zinc group, including zinc (Zn), cadmium (Cd), and mercury (Hg). These elements have distinct physical and chemical properties and are widely used in various industries.
Transition Metals Are Good Conductors of Heat and Electricity
Transition metals have excellent electrical and thermal conductivity due to the presence of delocalized electrons. This property makes them vital in the manufacturing of electrical wires, components, and heat exchange systems.
Group 3 Elements Are Called Scandium Group
The elements in Group 3, also known as the scandium group, include scandium (Sc), yttrium (Y), and lutetium (Lu). These elements possess unique characteristics and are utilized in diverse fields, ranging from aerospace to medicine.
Group 11 Elements Exhibit Coinage Metals Properties
Group 11 of the Periodic Table comprises elements known as the coinage metals – copper (Cu), silver (Ag), and gold (Au). These metals have been historically used to mint coins and possess desirable aesthetics and corrosion resistance.
Group 14 Elements – Carbon Group
Group 14 consists of the carbon group, which includes carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). Carbon, being the backbone of organic compounds, exhibits a unique ability to form diverse structures and compounds.
Group 4 Elements Are Known as Titanium Group
The elements in Group 4, known as the titanium group, include titanium (Ti), zirconium (Zr), and hafnium (Hf). These elements share similar properties and find extensive applications in industries such as aerospace, automotive, and medical.
Group 15 Elements Named Pnictogens
Group 15 elements are called pnictogens, comprising nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). These elements play crucial roles in various aspects of life, from supporting plant growth to being key components of semiconductor materials.
Group 7 Elements – Halogens
Group 7 elements in the Periodic Table are known as the halogens, including fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogens are highly reactive nonmetals, readily forming compounds with other elements.
The 18 captivating facts about Group (Periodic Table) we’ve explored are just a glimpse into the vast world of chemistry and the significance of this essential scientific tool.
